Bought three pairs of Zeiss glass lenses sunnies', 35 years' ago, with legal maximum anti-glare.
One is 'everyday', one is 'spare', & one is for long-distance driving, & horse-riding.
About 10 years' ago, got Prescription pair, for book reading, on daily work commute, by train.
'Lashed out' & bought Oroton pair whilst they on Sale. Haven't worn them yet!
MUST have metal frame, & 'arms'. Sweat way too much for plastic ones.
My 'daily' wear ones' have had a lens replaced twice, & so too, the arms.
Wear them inside S/C's as well, & on rainy days, due can't stand the G L A R E!
